Can you eliminate the rear system? Yes. But if you are going to pay someone to bypass the system, the time it may take to disconnect, bypass, and recharge. Very well could be the same time as to repair. So you will only be ahead the part.
If the corroded area is on the low pressure side, then a "repair" rubber hose could be used. If it is on the high pressure side, your repair hose and hose clamps will not last very long.
Same with the patch kit, low side can be patched although I haven't had any luck with those kits. If you are going to try it anyway, use an inexpensive 2-part epoxy like "JBweld" use a wire brush to clean and some electrical contact cleaner (leaves no residue) then apply your patch. HIGH side no patching will hold up to the pressure.
It is a labor intensive job to remove those back lines, under the vehicle trying to get all the clamps loose, then fishing the very long line up through. Interior panels to remove etc etc.
The the reinstall of all interior trim. If it isn't right, you will have squeaks and rattles you never had before. So it takes more time and care.
The line itself is likely expensive, price that yourself to compare. As far as the labor: if it something they do pretty regular 6-8 hours is reasonable for COMPLETE line replacement.
My question: How bad is it leaking, does it leak out over night? Or will a charge last a whole season? You may have to consider the cost against the use, if it will last the season.
