Kudos to you for trying to help in this situation.
You are spot-on about the trim. It is never too soon to get the hoof capsule realigned to the internal structures. In fact, the sooner it is done, the better because you don't lose time growing compromised hoof wall and connections that will then need to be corrected for while they grow out. For the life of me I cannot understand why vets/farriers advise waiting when there are documented trim issues. The longer you wait the worse the situation becomes as long toes and underrun heels tend to take on a life of their own. They will defy all attempts to rein them in if those attempts are half-hearted, slow and/or conservative.
When toes are too long the laminar connections take a hit with every step the horse takes. Once the connections have been torn due to a rotation/founder, this long toe is tearing at the same connections that are already severely damaged and fragile. If the heels are also underrun then the weight of the horse is not centered correctly over the bony column and the tendons and ligaments are also being over stretched at all times. It's a train wreck in the making.
As long as the horse is not on NSAIDs that are masking pain, turnout in a level area for gentle self exercise is ideal. No forced exercise until there is at least 1/3 to 1/2 of the hoof capsule that has regrown correctly.
