Without SMT mask! (didn't see te point to include that).

Would it be possible to add a mechanism that lets you change the CPU speed from software?

Everything is possible, just not in this format.
Unless you want to completely re-design the circuit...

So how much could you sell a mounted board for? I'd like 1 or 2.

I can't answer that right now. Have to get necessary components, spare time,...

QFP is good, I would say use the 8Mhz version. If it is switchable between standard 3.58MHz and double 7.16MHz that is enough imho. WRT production I would think there are enough people in Europe who could build these in batches and also build it into people‘s computers (for everyone not competent/confident enough to do it themselves, myself included).

Can't seem to find that 7.16 MHZ value.
7.3728Mhz is the closest thing to it I can find.
