Hello guys, first post here. Long time lurker, first time register/post

I was just wondering... I wanted some nice new keycaps, was thinking of getting a Filco but that's nearly impossible in Canada, so I got a Das (still wanting that white Filco tenkeyless... :O) I have a Das Professional S Silent model, brown switches in them.
Will these fit on my Das well? Not too odd in shape comparatively to the other keycaps, etc.

Thanks!
EDIT: if anyone knows a great place to replace all my Das keys with nicer ones (double shot perhaps?) when they wear off more, I'd be happy to take a look.
