You’ll be ok as long as the JB Weld lets go at the same time on both mounts and not just one.
I have a crescent shaped cookie cutter type scar on my forehead from a scope that let go years ago, though the scar has faded significantly as time as passed. Basically the mounting screws were too short to properly hold in the tapped holes in the barrel/action (factory installation) and they ripped out on the first shot, destroying the gun, scope, my glasses and forehead to the tune of about a dozen stitches. Can’t mention manufacturer due to an ‘agreement’ with them. With the ‘scout’ position of your scope, doubt you will have a similar event, just a potential accuracy issue.
