Dually Spare with Standard Front wheel question

[Raggedy Andy]

Hello. Not new to the diesel world however I am new to the Dually Diesel world with the 2025 3500 I just purchased. Sorry if this has been asked but I couldn't find it. I am going to lift and go to 37's, thinking I will keep it DRW since there are no suitable load capacity light truck tires to go single without losing 1000 pound capacity (whole different discussion). If I change out the fronts to a different wheel so I can have wider front tires, couldn't I just carry a dually wheel spare tire and put it on the front inverted like the outer on the rear, since the spacers would need to be removed, for a limp home or at least out of the hills? I understand that I may need to carry an adapter if the spacer is a different lug pattern than the hub but that's not much extra to carry. A good example of this would be using Nitto Recon Grappler 37x11.50R17LT on the back and 37x12.50R18LT on the front.
Just trying to think this thing out.
Thank you
