We sort of did something similar back in the 70's and early 80's but in reverse. Back then we only had between 7 and 9 taps, 3 on sugar maples, the rest on box elders (ash leaf maples). We simmered everything on the wood stove in the living room, with 2 windows partially open for a cross breeze. Then as it neared syrup density, we boiled it on the gas stove in the kitchen to finish it. It worked fine. I see no reason it wouldn't be good.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
