As a result left-handed Spaniard Lopez will be contesting two finals on Sunday, including his first in singles since winning the prestigious pre-Wimbledon event two years ago.
"It was a good match".
"If I keep progressing, I would like to try to play singles", he said.
The Briton underwent major hip surgery shortly after but responded well and returned to tennis at Queen's ahead of next month's grand slam at Wimbledon.
Murray and Lopez - the latter "fresh" from winning the singles title less than an hour earlier - beat Britain's Joe Salisbury and Rajeev Ram of the U.S. 7-6 (6) 5-7 10-5 after a third-set match tie-break.
Murray, who said he felt zero pain in his hip but that his back was stiff and his arm exhausted from serving, said he had not expected to get this far.
"I'm exhausted, of course", said the 38th-ranked Frenchman.
The second, and more exciting option for Murray fans, would be for him to start practising his singles immediately after Wimbledon and then play the Cincinnati Open starting on the 11th August.
Andy Murray is on the verge of completing a remarkable return after hip surgery.

This match provides an interesting clash of styles, with the Spaniard certainly being more suited to grass. "But I still have to improve quite a few things, like, physically". "It would be nice to play at the US Open but if I don't - look, I got so much enjoyment and happiness after winning a first-round doubles match here that, you know, that's enough".
A couple of sweet Lopez volleys put the duo 8-4 ahead and Lope crunched a forehand victor to bring up match points.
Lopez, 37, was clearly impressed.
Murray and Lopez, though, were not to be denied and, despite some nervy moments in the champions tie-break, they came through and just about had the energy to embrace each other and raise a hand to the crowd at the end.
The second set was equally close, with both pairs fending off break points until Salisbury and Ram finally secured the first break of serve in the match.
In the decider it was Auger-Aliassime who looked jaded and he was broken to love as Lopez went 3-2 up.
