I only have a 32" inseam (6'2" but long in the torso) and have never had the least bit of problem reaching the ground with a Russell. When I flat foot it I can still have my knees are bent a little, and that's without skooting forward. If you really have a 30" inseam I can't see how it would be as bad as you say. I'd be interested to see some photos of your seat to compare the builds. One other thing to consider would be sending it back to Russell and have them lower you. If you had told them that reach to the ground would be an issue with you they would have kept the rise to a minimum.
I also have on a Russell on my Vstrom DL1000, which as you may know sits quite a bit higher than any FJR. I'm on tippy toes on the 'strom with the Russell, but I don't care at all, and would actually like it to be a bit higher (for ground clearance). Anyone who has ridden dirt bikes or dual sports much becomes pretty used to a high seat height which means one-footing it at stops (a good practice anyway) and dismounting to try and back the bike up. You do become more adept at always finding parking spots pointing uphill, so backing out is easier. It is well worth that trade-off (to me) for the all day comfort of the butt zone..
As for the reach to the bars being greater, yes that is definitely true. I really would not have needed bar risers on the FJR, but did for sure after getting the Russell. I got the Heli risers which go up ~ an inch and back an inch
