Class T Lynx Power In (M10) to Lynx Shunt (M8) or Class T in Lynx Shunt

I have discovered that the CNN fuse I am using as a main system fuse in my Lynx Shunt is not adequate for my LiFePo4 batteries. I am looking at replacing my Lynx Power In (M8) with a Class T Power In (M10) to obtain the correct Class T fuse. I would have to drill out the holes in the Shunt (M8) to accept the Class T Power In (M10). I would also have to replace or drill my M8 cable lugs from my batteries. Would this be recommended?

Another alternative that I am trying to learn more about (saw it posted in the archive community) is utilizing a Littlefuse LT17 or LT15 fuse in the Lynx Shunt. They are expensive, but not as much as the Class T Power In. Does anyone have any more information on using these fuses in the Lynx Shunt. It appears it would fit from a pic in the archive post…
