These are the differences between UK and the NORDE kit that Wodan proposed.
The yellow keys are optional.

I'm not seeing the miss match here. UK, DE, Swedish/Finnish, Danish, and Norwegian are all covered. While I did base it on Wodan's kit I did make a few small changes and I based it on UK ISO since ANSI was not the goal.
Would you consider to include Dvorak(English) add-on kit on this classic set?
I won't, it requires too many keys for a relatively uncommon niche that would be better handled by a uniform profile.
Thank you Sir. I would join still if you would ship to Hong Kong in affordable shipping cost. 
Hong Kong shipping will be possible, but I can't say what the price will be yet. I believe it will be the same price for everyone except swedes, though!
If I'm jumping on this I would like all legends correct so for me you need to include @ on 2, £ on 3 and \ on + so that all keys are "swedish".
For me I would say that I have a larger need to insert "extra" keys such as a function key to the right of right shift on smaller boards. I do not have this need on a TKL. And if you are considering changing rows to match 65% and 75%, I would say that it's not fully TKL compatible. I'm not saying that this is bad. Look at the kit that Zennasyndroxx made. I love it with all the special sizes of keys which lets me configure my GH60. So it's more important for me to have legends correct than compromises. symbol on E and ΅ on M would be a bonus.
As I discussed briefly earlier, the philosophy behind the set is that all secondary legends must be correct, but tertiary legends (including and mu) will not be included if it means the set will require more keycaps.
The change I proposed was to make Del, End, and PgDn R1, nothing else. I agree that it's not truly TKL compatible but since it's not part of the main cluster it's pretty negligible. Just wanna make sure we're on the same page

In other news, updating the image tomorrow. The tilde (dotted R1) key will be replaced with a blank unless we can come up with something better.
Maybe you could have a community cap or something else that's a bit more fun than a blank?
Maybe reuse some existing novelty cap? (please not the cherry-icon tho)
Since it covers HHKB-layout, I might join it for the good cause (if I can afford it when it goes live), the Swedish caps might come in handy some day, you never know 
A new novelty cap would increase the price more than I'd like. Reusing a novelty cap is not a bad idea, but I have no clue what we'd actually use in that case. Since it's a minimalist set, I'm not sure if there is anything that will fit and look better than a blank.
Wouldn't be worth replacing ANSI keys with NorDe equivalents rather than having both?
The only ANSI caps included are left shift, enter, and pipe (blank).
Not those. I mean the number strip and the non alphabetic keys.
Something like this.

Those are ISO UK 
Not sure if it would annoy other people but any chance of the 4 key having $ and symbols on it?
Nope. That is only part of ISO UK. ISO DE does not have the sign there, so we're skipping it.
I don't like the idea. Releasing popular sets with an optional NOR/DE works well enough. We get a great set, and a chance for a NOR/DE set as well.

Yeah, but what you get here is a WoB set with nordic legends.
This will never reach MOQ, as the only reason for getting this is the nordic legends. Very few others will buy it. So it will still have exactly the same issues as any nordic addition to other sets, which still have the advantage of being popular to the 500+ MOQ limits.
I understand the skepticism but I also believe there's a few good reasons this will succeed:
1. It's being shipped within Europe, reducing shipping prices.
2. It's also not subject to import tax, which can be very steep.
3. It's being run minimum profit, meaning it will undercut competition pretty well.
4. There have been few successful international kits, resulting in german and nordic buyers often being left out. UK tends to have a bit more luck but it's often not true ISO UK and just ANSI + the three extra keys.
All in all these factors will contribute to a pretty large amount of potential buyers with strong incentives to join in.
