Hello and welcome.
How much different in size and in which direction? I presume you mean the diameter of the groove mount on the Merlin is smaller than the groove in the titan? Should be easy enough to design and print a sleeve to fit over it so that it fits. How's your CAD?
If you are unsure how to do this post the dimensions and some photos, I am sure we knock up an adaptor easy enough.
