I think the community can likely handle this adequately by using laminating film and/or transparent vinyl dye-sublimated adhesive stickers on the Clear RGB layouts provided by Framework. See some existing vendors and discussion in
Keycap stickers for the clearcap options.
I would rather Framework use their current limited resources to enable more hardware keyboard variations, before working on custom keycap printing (although eventually having both would be best!) For example, Framework currently only sells Clear RGB for ANSI and ISO layouts. It doesn’t sell a Clear RGB JIS layout, nor a Clear RGB Ortholinear layout, nor a Combo ANSI/ISO/JIS keyboard layout
Also see Designing a deeper chassis for "mechanical" keyboard module. It’s pretty difficult for the community to make custom hardware keyboard layouts because Framework doesn’t leave enough space for common consumer low-profile keyswitches.
