Since both species share the same karyotype of 2N=40 this hybrid is entirely possible!
FOr your interest, here are some ploidy counts for other members of the genus. Matching karyotypes are all possible candidates for hybridization. Thanks to the CP Listserve for this data, used completely without permission because stealing and sharing data is a learning experience!

I wonder what a Drosera peltata x Drosera neocaledonica would look like!!!
