If you plan on ever competing with this gun in the future than ther is a few other things to consider, like weight of rifle trigger and stock configuration. But if your just going to use it to go to the range and shoot a few rounds on the weekends then you will be ok with just a switch barrel. I have a Nesika with a 308 boltface that shoots a PPC it was made that way. The boltface on your Nesika is probably a sliding extracted typ( not a sako typ extractor) it can still work for extracting PPC cases but if you go that rout make sure you use a gunsmith that knowe what he is doing
