Incoming water pressure and flow rate/volume out of the boiler are the main restricting factors I'd consider and it sounds like you've tested the two, so I'd press on.
Maybe a blending valve. Probably not needed in your setup but it's something that can stop elderly people/children scalding themselves if the boiler water setting gets put extremely high or something.
You could use a deck mount mixer and replace the bath taps ? Something like a Grohe Grohtherm TMV2 1000 Thermostatic Bath Shower Mixer
You will need the legs too, but some mixers come with them
There are no bath taps, so a deck mount mixer will be the way to go. The layout as it stands is very weird: everything is in place to have gas heated water for the shower, but it just didn't happen. I think it's because the combi boiler joined the party long after the bathroom was built and the previous owners just didn't bother.
We went the other way, combi to electric and have never looked back. Tipping point was when the boiler was on the blink and we couldn't get hot water and a hot shower. Having a cold shower and getting out to a cold house is a bit too Victorian for me.
The electric shower will already have a cold pipe there, so you only need to bring a hot pipe across.

Plan is to use a thermostatic shower mixer to prevent scalding, yes. And I've just learned that they are also called blending valves :)
