Removing Lynx Rush is more than a good idea imo.
So far the only button I'm really missing from the button cut will be scatter shot.
Making Stampede a talent is fine too imo. I found stampede to be extremely underwhelming in all honesty. Picking between a DoT, my pet hitting harder, or a bunch of pets on a 5 minute CD though... I see AmoC being the biggest for SV/MM as I imagine most people will run Versatility. Blink strikes will probably remain the best talent for BM. This means that stampede will just be too long of a CD for the damage it gives. It will need some sort of buff to be worth speccing.
