I would buy this IF you went with either DSA or SA profile, and here's why - myself and a huge bunch of retro fans have missed out on about 5 different retro-style keycap sales in the last few months. This brown combination is very 70s, and with a DSA/SA profile, you would get many buyers like myself wanting to fill their retro void. You might not realise just how 70s this colour scheme is, and how successful it could be in the retro market.
SA market's flooded and SA tooling is backed up for a good long while. If you're after retro, check out Green Screen
I think that'll be an awesome set "in the flesh". DSA is just not popular right now, for many reasons, so I don't think it's the best choice. Also, the OP wants Cherry legends, which are only available on DCS or from GMK and JTK.
I have high hopes for this running as a JTK set. DCS is acceptable for those who like the high pitch click of Blues, but I don't buy anything nowadays that's not either Cherry profile (with low angle bottom rows and really thick) or SA.
The only one that could change that is Devlin's "Q" profile if anything ever comes of UKKeycaps' discussion with them.
