I think it may be worth a shot since tires are relatively inexpensive. Is there any caution against mounting 32 or 35 tires onto an 19mm rim? My bike came with DT Swiss P1800 splines. What advantages would I have to getting a wider rim down the road if I wanted a dedicated entry-level gravel set? Do wider rims mean even lower pressures?
No worries about running 32-35mm tires on 19mm rims. This used to be standard for MTB and until recently it was default for cyclocross racers to run tires in this range on 19mm internal rims.
Wider rims will generally improve the handling with wider tires run at lower pressures. The tires have a lower profile when mounted on wider rims, and the sidewalls are more supported so the tire doesn't roll over as much in corners.
