Can anyone see any snags with this? Obviously I want to do the load bearing
floor such that when I do the loft conversion for real, it is suitable, so
any suggestions appreciated.

Sounds reasonable enough... you may have to do something slightly "non
final" at the loft hatch otherwise you may find yourself with a joist
flying right over the opening making access difficult.

Depending on your loft hatch you may well find getting long beams into
the loft space impossible without making some form of access hole
through the side of the roof. Having at a minimum some scaffolding tower
in front of this would be a good idea. Next time I do one I would also
put a jib on the top of the scaffold and add an electric winch!

Think about where you may need dwarf walls, or other supporting
structures since you will need to size the joists to carry these point
loads as well and not just the uniform distributed floor loads.

See if there is anything else on my floor construction page that helps:
