But seriously there's no need for it
Actually, for now, there is. Otherwise, Guile would not be playing as the RHD on the first pair at D.
Finding a short term, 1st pairing RHD, while Reinbacher continues to develop and adapt to NHL-sized rinks, is not a given in the least.
IMO, Guhle - Reinbacher, right away, is definitely not an option. Guhle-Mailloux ,is also not an option, at least not for now. Guhle - Savard is a horrendous pairing option for a first pair on D; Savard already has trouble in a 2nd pairing deployment.
What other option do you see from within? IMO, there aren't any.
Getting one fromqoutside the system that helps Guhle develop as a 1st pairing LHD is also highly unlikely.
I can't see your magic scenario that is better than the current one, for the short term, anyhow.
Please outline it for me so I can assess its value and feasability.
