You will need to study both MUGEN characters and take all the sprites and sounds of that particular hyper move and re-arrange and re-adjust for use in your target one! Not to mention you also have to deal with any conflicts when trying to combine stuff like that........
Oh you just made me remember how I tried to take Shin Messatsu-Goshoryu from Infinite's Evil Ryu and added to mwryly's Evil Ryu, and mwryly's Evil Ryu was added something new like Ryusokyaku to PotS' Ryu............
