Give it a go... I've seen some excellent prints at that size made from 35mm. That said... you'll need the supporting infrastructure, easel, trays, large enough washer, drying rack, etc. Not sure if there are any labs near you, but I tend to get help from a local custom lab for bigger prints. 16x20's and 20x24's, though I could do the 16x20, I tend to make an 8x10 or 11x14 guide print, then have a professional printer make the bigger prints for me.
