I definitely would re-think it... You sense the convertor unlock... so you force a downshift and make it lock again (incurring wear), rather than just let it run unlocked and incur NO wear? Heat? Cars and trucks and Greyhound busses had torque convertors that *never* locked under any circumstances up until the late 1970s. The heat generated is less than you think, and the transmission can dissipate it easily.
"Hunting" is a different thing altogether, whether it be hunting between gears or hunting between lock and unlock. That's a case where intervening and just holding a lower gear is definitely a good thing.
