Yeah a rebarrel on an old action will cost more than a new stainless howa in the same caliber.
See if you can find a second hand 308 barrel to fit, chop it to 16 inches and load for your twist rate
The logical thing is to trade or sell the bsa and buy what you want in standard configuration, not that i enjoy raining on your parade but I only rebarrel what I'm really into to get something non standard that's worth sinking the $1000-$1100 it costs to rebarrel
