14s100p 18650 plus 16s 280ah lifeP04 can they live together?

Okay, I find myself in a possible situation to mate the two different chemistry batteries. Goal WAS to replace the working 18650 battery with the LifeP04 battery. 18650 = about 13kwh and the LifeP04 = about 14kwh.

But I have been thinking while I wait for the LifeP04 pack 8 cells at a time to top balance at 3.5v @ 15amps via iCharger x6. What if I matched the voltages of the packs then via switch join them in parallel with settings on the Sol-Ark 8K to accommodate both chemistries, say 45v cutoff and 55.2 max with 60amp limit charge and discharge.

Voltage would be for the 18650s: 3.21v to 3.94v (fairly conservative), for the LifeP04: 2.81v to 3.45v
Each pack has its own BMS.

Has anyone done this? Pros and Cons?
