Been thinking of doing the same with mine.
Cheapest options is probably to fit 620 Heads (complete) and 620 Barrels and Pistons. Trouble is sourcing them. Otherwise go with a complete 620 Engine (ideally not the Multistrada)
Then try and find someone to lift the 750s Rev limiter (mines set to 10500 rpm) and also reprogram the fueling. FIM software use to do this as does Techno Research's Direct Link software and Dongle. Not sure if the Software Chris at CJS or Mark at BSD can do it, probably worth a phone call
Andy Challis run with a Standard 750SSie ECU setup by MArk at BSD in Peterborough as far as I'm aware and not only won races but also broke Class A lap records, hate to think how well he would have gone with 1500 extra revs available to him
Stick with all of the 750 Electrics, Tacho, fuel pump, injectors etc
I say stay with the early injectors as they match the 1.5M ECU better, the Pico Injectors off the 620 don't fit the 750 throttle bodies and flow 20% more fuel, so would leave the mapping a lot of work to do
This method means you have nothing to do with coded clocks, coded ECUs or keys with Transponders.
Also you don't have to worry about the weak point of the 5.9M ECU as used by the 620 where it is possible to loose a ignition coil output driver leaving you with a single cylinder as it did with me at Snetterton this year and Pembrey Last year, on both occasions they were wet races. Many of my connectors are now filled with Flowable Silicon to hopefully prevent this happening again
