You can do that (obviously, it works!), but I'd recommend you just use a channelizer with N=125 instead of 117! Your channel map can be used to ignore the channels you don't need (which seem to be the 4 upper and lower "edge" ones), and by only increasing the workload of the PFB ever so slightly (probably even actually decreasing it, because an 125=5³- FFT is likely to be much more efficient than an 117=3²·13-FFT), you get rid of the rational resampler, which not only brings more CPU load, but also a resampling filter response that might have ripple and aliases.
Thanks for that suggestion, Marcus! I have the resampler version running right now but will change to use the channel count idea instead.
