Of course we are interested in optimizations. An example of how they
can be integrated is available @
(this is for VP9, but the idea is similar).

For HEVC we already have some of the ground work available such as
libavcodec/arm/hevcdsp_init_{arm,neon}.c , latter of which is what
sets the DSP function pointers. You can see if your existing SIMD can
fit into any of the functions that are defined by the HEVCDSPContext.

Best regards,
