Yes, this caliber in very potential with modern gunpowders and bullets; bullet caliber is same which .404 Jeffery has and you could now reclaim from 10,75x68 at least same power as .404 has when it appears in 1905. Suitable action is very easy to find because any .30-06 -lenght will do. The only problem is the price of shells but if you buy, for example, 50 pieces at first time they will last many years if you handle then correct way.
