If your not trying to kludge it as a fusion... Rescue Rangers already has at least two (low to middle level) sparks as reoccurring characters that I can remember. Gadjet and the short balding scientist.. in fact they had an entire episode where him and Zipper switched heads due to a telporting through the phone line device. It was a 'The Fly' parody... but the big reveal was that the scientist found out that the RR were not just dumb animals, but actively screwing him over on purpose.
Add in that they have a reoccurring bad guy that could be one of the offspring of the king of cat... and the crossover is more 'Time travel episode in Europe' than anything else... Gadjet could actually be the result of someone trying to make an organic artifical spark (Agatha pulled that off literally in her sleep, after all)... fudge the hair color and Gadjet and Agatha could be directly related... through Science!!! and genetics.
The link is that at some point in the past/future (for GG) someone bioweaponed (microbial) the populous and now super sparks are reduced to the level of the RR characters. This means most sparks simply can't break through.
In short this plot writes itself... and Dale being descended from competent minions would explain much.
