Nup no pokemon can be recruited in the dojo even if they have a high chance of joining normally.
The only place you can get one is floor 89-98 of western cave and they have a -33.9% of recruitment so with the max 34% bonus it only has a 0.1% chance of joining. ;123;
No there are lots of pokemon on floors 1 & 2 with quite high recruit rates but it isnt possiblt to recruit there.
I think all the starters highest evolution have a -33.9% recruit rate. ;123;
