Depends on how much work you want to put into it. For the Tamiya FLETCHER kit, the crane and catapult is a large part of the conversion, but there are other things that need to be altered as well. The two aft deckhouses were joined by a solid deck to facilitate handling the aircraft. That can be scratch made. The main deck 20-mm guns and K-guns need to be moved aft and the 5-in gun practice loader moved to the starboard side. However, the Tamiya kit has some errors around the aft end of the island and main deck area to fix. They placed the foremast in the wrong place as well.

I have the iLove kit and have been working on it. I will say that even though iLove is apparently under the Trumpeter umbrella, the quality of the basic parts and details in general is superior to both the now very old Tamiya kit and Trumpeter's poor excuse THE SULLIVANS kit. The weapons are best replaced with 3-D printed items. My biggest headache with the iLove kit was trying to model the catapult and crane with PE. The catapult may be built up close enough. But the iLove crane is wanting in shape accuracy (it folds up in ONE position, not quite either stowed or deployed, and doesn't have the hinge to change the angle from stow to deployed) and lack of some equipment. I suspect that ILove depended on the USS HALFORD inclining photos which only show the starboard side, not the stowed crane on the portside. The Black Cat crane allows for posing the crane in a stow placement or in the retrieval placement. Anyone who wants to diorama this kit showing aircraft retrieval would need the Black Cat crane.
