First off, 'XT3' and 'CT4' should not happen. Lineup spread too thin & they are redundant.
XT6 should have merely been a 3-row 'XT5 ESV'.
I would add an AWD XT4-V and XT5-V.

Can the 2.7 even be used in transverse applications?

With a new dress cover and oil pan, I don't see why not. Height really isn't an issue at +15mm. The stupidly long oil filler neck needs to be replaced and the oil pan need to avoid the front sub-frame in a different way. Neither are stressed elements and it's not rocket science. Arguably it's less effort than designing a muffler.
