Nope, the rear triangle is toast. If you "bend" it back and "fix" the crack, you didn't fix it correctly and have no concept of the correct ways to fix/restore frames.
That framest requires a new rear triangle, and the chainstays must be carefully ground out of the BB. The seatstays can be repaired by using shorter sections with an internal sleeve if the repairer wanted to maintain the factory seatcluster union (internally lugged, would add a few grams) and would make that portion of the repair easier.
You would put the frame in your building jig, and determine factory BB height. Cut the chainstays short, and start grinding, taking the massive heat required to pull the chainstays clear would be foolish. The Repairer would then use heat propogation control paste around the seat-tube and down tube unions, and would use silver solder (if you got the gaps right) and redo the chainstays.
The above method would be the SAFE and correct way to do it.
Sometimes you have to let it go, that frame is a candidate for a framebuilder. Buying that frame is "Penny wise-pound foolish". WALK AWAY.
