The only issue I know of would be if a Judge in Tx issued a bench warrant for your arrest. AFAIK - and I'm not a lawyer - that could be a problem if you're stopped anywhere in Texas and the officer finds the warrant. Outside of Texas, it's not likely that the warrant for a traffic infraction would show up. It's also unlikely that any other state would do much of anything in regards to an out of state warrant for a traffic infraction.
All things considered, it might be worth contacting the local prosecutor by mail, explaining you'd like to negotiate a solution and see if you can get down to the original fine or less. I'd expect they'd be willing to take just about anything vs. nothing.
