YES!
And ideally with a fitting waveguide to combine with the tweeter.
But not sure if this will happen, it doesn't fit their lineup well. But boy ... a 3,5" dome fitting their big tweeter and going down lower as the 3"s ... I would think seriously about by building my reference speaker new for the last time - again. 🤓

Mmh, there are M174 + T34 drivers from Bliesma available that might fit the needs to achieve more SPL than M74 + T25, at least I assume these are made therefore by providing more membrane surface and more thermal capability by larger domes, coils + motors. Or take 2x M74 + T34 like @profiguy. Purifi 1.5" tweeter has very nice performance but appears a bit overpriced to me in comparison to T34A. But another good option would always be welcome.

Regarding the SPL topic in general:
3" mid-domes from Bliesma and Volt available to the DIY cowd can provide clean peak SPL range up to >115dB@1m, with the advantage of very low thermal modulation, wide dispersion and lack of resonances in the passband, and that is very loud in comparison to usual high quality 4-5" cone mids.
While this is valid in comparison with "typical HiFi cone drivers", there are out 5" PA mids that can also deliver SPL in such range, some are really nice made and have shorting rings and caps. I remember distortion measurements in german DIY forum of a Faital PA mid with low distortion @110db, and the manufacturer distortion measurement of this 5" BMS midwoofer is also nice. There are other 5" PA drivers out that look tasty, TSP based sims show that 110-115 dB is often usual peak SPL capability.
So, can a good PA 5" mid be an alternative to expensive 3" mid-domes from Bliesma and Volt for high-quality-high-SPL applications?
(Of course dispersion/radiation will be narrower with the larger 5" cone in the passband - but i see this first as a property, not a drawback.)

I'd have to say no, simple due to the larger VC and higher base sensitivity, including the cleaner off axis performance and better transient response from lower Mms.
there is no such thing. Mms factors into the sensitivity and TSPs. that is it.
