I agree, that sounds like a good plan.
But be sure you use a large enough master cylinder. Whatever the bore of the stock one is is about what you want for the new replacement. I fear that the ones sold with the kit won't be big enough.

Not entirely relevant, as I have large disc brakes on my truck, but my system needed a 1.625" bore MC, a good bit larger than what would have come in a "kit" designed for the smaller trucks.

Do some checking and measuring first.
