No, I don't think so. That's why he wanted that LW title fight so soon after his FW title fight, because he doesn't plan on getting down to 145 again. He wants to have two belts at once, and the longer he waits without defending the FW belt, the closer he gets to losing it. He's too big now, so he needs to get the LW or WW belt ASAP because it's going to be hard to convince them to let him keep the FW belt locked up without defending it for too much longer. Luckily for him the division is not popular with casuals, though, so he may be able to buy himself another 6 or so months. He's gotta win the LW/WW belts within that timeframe, though, in order to fulfill his goal as a 2 weight champion. After that, he'll relinquish the FW belt.
