Use of Silent Partner + Grigri

I was wondering if it's possible to use, during rope solo, a grigri at the same time as a Silent Partner, on a SEPARATE line. The reason I ask is this: say during a fall, the grigri fails to engage because you're not completely vertical or the rope goes sideways or whatever. If this happens then the SP on the second line should engage.

However, for the SP to engage there has to be enough torque present on the line going through it. So even though the grigri fails to lock on line one, could it happen the there is enough friction going through the grigri (or around it, whatever the case may be) for it to slow you down just enough to prevent the SP from engaging, and then you're s.o.l?

I know knots are the way to backup an SP, but we were discussing whether a grigri already attached on a separate line could be the backup (or primary, or whatever) and the SP on a second line being the fail-safe.

That way no knots are needed, and also when ready to descend you use the already-attached grigri, and don't have to fiddle with attaching it up there. Also you can just take a break during the climb if needed, and hang on the grigri.

All hypothetical btw, we just could not reach a consensus whether the line going through the grigri could possibly interfere with the torque required to allow the SP to engage in the event the grigri doesn't lock. Thx.
