can I swap out the 105 chainset for a 46-30 grx double without changing anything else for easier gravgrav ratio?

You have to lower the front derailleur, and shorten the chain obviously.

You’ll probably also need to change to a GRX front derailleur, because of the 2.5mm offset GRX chainrings. Although some people report that their road front derailleur also worked, by adjusting the limit screws to their limit.

nice one. it's a band on mech so probably worth a try.
I'll probably slap a new chain on there anyway.

edit - just found a thread on stw forums that suggests 11-40 cassette and a roadlink would also work. might be a better option as I'll still be able to ride the big on the road.

Nah, can run 105 with 11-40 without roadlink, best to test to make sure the derailleur hanger of said bike allow this.
