A common misconception about the Daleks is that they are robots, however they are really more cyborg than robot. Hidden inside the casing of the Dalek, unseen, is a Kaled mutant. And this is where my suggestion comes in. My suggestion is to add a rare chance that upon death, a Dalek will mutant will survive the destruction of its protective casing and attack the player. In simplified form, when a Dalek is killed, it'll spawn a Kaled mutant. This mutant will onto the player and attempt to strangle them (like in 'Resurrection of the Daleks'). The mutant would have around 3-4 hearts, so it can be easily killed by the player. opon death, the mutant would drop rotten flesh.

Other suggestions by me:

After doing a bit of looking around on the forums, I found Arc's skaro thread where there is also a segment on kaled mutants (Though that bit was thought up/written by 50ap5ud5):  https://swdteam.com/forum?p=thread&tid=119
