? Volvo Chemical Gasket

I just came up with this idea and wonder if you guys like it.

Those of you who owns Volvo know that Volvo use "Chemical Gasket" (Anaerobic gasket)to seal the cam head and the oil sump.
Volvo PN 1161059: $30 for Volvo OEM or $7 for Victor Reinz brand

The procedure is here:
The Volvo procedure says use a roller but you can still use this like an RTV sealant (silicone based).

So my $1M question is, if someone is willing to be the guinea pig, then he/she can try this WITHOUT the need to remove the subframe/oil sump. It is an 1h job instead of the 10h job!
- Drain engine oil.
- Loosen the drain pan bolts, support the rear part of the sump with wood/floor jack.
- Now remove the sump bolts and cut the old gasket and remove it.
- The FRONT part of the sump will rest against the subframe; The REAR part of the sump will rest against the floor jack; and gives you about 1 inch of gap to apply the sealant.
No need to remove the oil sump.
- Apply the Volvo sealant all around as per Volvo procedure.
- Bolt the sump back and that is it.
- Oh, don't forget to add the engine oil!

This is the Volvo part I mentioned above, PN 1161059:
