Would there be any problem feeding the antenna and pre-amp with CAT-6 cable?
No, there would be no problem, this a a proven technique. Te original LZ1AQ AAA-1C? active loop is using twisted pair Ethernet cable as feedline, power supply line and control line..

"Ethernet cables are designed to handle frequencies that coincide nicely with most of the interesting amateur radio bands, and their insertion losses not much worse than RG58. The twisted pairs are also a balanced system that’s good at rejecting common mode noise. Cat 6 cable also has four pairs of conductors, allowing you to feed multiple antennas with one cable, or to distribute power to amplifiers and switches along with antenna feeds."
