Another leaf spring question

My leaf spring saga continues. I just finished pulling the old springs and found a pretty rusted area on the front side of the driver's side frame where the bolts for the hanger come through like so:

The other side isn't bad:

This is the same spot after some "percussive maintenance" to break most of the loose stuff off...

The hanger kit I purchased came with a reinforcing plate that will mount against this side - effectively sandwiching the damaged portion between 2 plates of new steel. Here's the plate:

In your opinion will the new hardware/plates be good enough or should I have a welder come out and repair this spot?
