I don't remember Alice being capable of passively reflecting anything. She is capable of stopping directional attacks, but what happens if she takes some lightning from a blindspot? What can Alice do if Met goes into a stealth and hits her in the back with a lightning bolt or if he turns into that lightning dragon and completely engulf her?
Finally the Leigong is 34% Ether and Met has shown that he has some serious passive defenses when attacking. I can't tell how protected he will be from Alice's hand orbs and how his specific brand of electricity will interact with Alice's power, but if he could punch Evander with impunity then it's possible that he can also trade blows with Alice without getting too affected by her orbs.
As for Michael, there exists the possibility that he may suffer adverse effects if he absorbs to capacity, but frankly this sounds like a good thing for him, not a bad. He has been stockpiling monster energy for weeks and his spells are powerful. Even MC had trouble staying near him during his Evolution Trance. I don't think there exists a scenario where Met will benefit from throwing enough lightning to fill him to capacity.
Remember her early training with MC, her barrier is impenetrable below certain power level, also she were shown circling a lightnin bolt around her fist during HERO invasion. Rina can be taken out with AOE attack, attraction or a bomb.
34% Ether gives him charge telekinesis. It's also pretty well known how Alice's powers operate. Your attack should be capable of overcoming gravitational barrier of a significant celestial body distance included (gravity is a space-time curvature). Unless Met has control fast and precise enough, his bolts will get dissipated or redirected.
Evolutionary power surge is temporary and poorly translates into power level after. But it's also likely that Michael will overpower lightning barrier with a focused beam or power dagger.
Met's passive defense and everything else is indeed powerful enough to engulf a person or two, I wouldn't argue about that. My point is that you underestimate Alice's a overestimate Michael's matchup against Met.
