Can we add deformable convolution at different places?

[knmac]

Hello,

Can we add deformable convolution at different places? More specifically, for ResNet50, can we add it to the 4th stage, i.e. res4a, 4b, 4c, etc. Do we simply add the deformable convolution operation, or do we have to move RPN and PsRoI Proposal to before the 4th stage also? Thank you.
