Is it possible to make an UFL Football Team if you never played NCAA Football or higher?

I am about to tryout for an UFL Football Team at the Wide Receiver position although my main position is Quarterback. I am 5'10 170lbs and I run about a 4.5.3 in the 40 Yard Dash (Scramble QB). It's a lot of receivers my size who makes it to these teams, but they played at least in the CFL. I did play Jr. College, but I had personal issues which led to not not being able to play for a university. I recently played 3 years of Semi-Pro Football, but that was at QB, WR & K-Return. Is there a real chance that I can make it over people who played on a higher level?
