Best is probably fleet corsair retrofit. Oddy boff layout, with an additional hangar. Toss this build on it and slot shield repair units for maximum heals.
Varanus (and/or its fleet version) is effectively the klink DSSV. You can use this build on it for reasonable healing. I haven't tried the repair platform myself; that might be a nice addition.
EDIT: Ah ha! Take that, scurry! Anyways, remember that these suggestions are aimed at pug healing; premade healing might dictate something slightly different. (Also, I haven't tried these evil dirty red-and-green klink ships myself, so take these ideas with a grain of salt.)
