Yes and No:Yes, the clip is part of the scale and you could swap it out to another 111mm knife.However, this brings me to NO; the OHT swap would require you to file out (cut) the scale so that it would properly receive the backside phillips screwdriver. Great idea but I am not hot on cutting up my nylon scales and second, your now "un-scaled" Sentinel would need a replacement since a swap from the OHT leaves a cutout where one is not needed.
Something like this...maybe
