Don't know if it's do-able with your bbls,,but I'd bet it has been done before.
The only one that come to mind that rebores and rerifles bbls that large is Bobby Hoyt.
His work is primarily (all?) in the black powder field but it's worth a call.
Contact him at 'The Freischutz Shop', 700 Fairfield Station Rd., Fairfield, Pa. 17320.
# 717-642-6696
No email or web. Strictly old school but among the best in the biz as far as the BP shooters are concerned.
Let the phone ring,,he'll get to it. Sometimes takes a little time with the machine(s) running.
He regularly rebores and rifles Muzzle loaders in the large calibers and gauges.
Makes bbls from scratch also.
Perhaps he can help with breechloading LCS bbls too.
