In short, no. It won't work with the Revell kit for a couple reasons.
One is the Revell kit is 1/32 scale so the parts are too small for the helo.
Second, the Dragon kit has the 6th rotor blade included since you get two identicle sprues for the rotor assembly and each has 3 blades, leaving one as a spare. Also, the new rotor head is made for how the Dragon kit assembles. The Revell one is very different in its assembly and parts breakdown.
Your best bet is to find a Dragon 1/35 AH-6J kit. Next bet is to use any other Dragon H-6 kit based on the 5-bladed MD530 kit. Only these have the extra rotor blade needed for the conversion. You would still be missing the black boxes and other bits found in the AH-6J kit though.
