If you satisfying with color grading DNxHD at 176 or 220, that it’s safer to transcode all of them to 25p base.
If you wish to color grade original clips in Resolve, so it’s needed to generate proxy in native fps.

As Glenn Sakatch said, just generate RED proxy in Resolve at native fps.
And do the same with other footage too – in Avid AMA-link and transcode them at their native fps, but each one in separate projects with different fps (23.98 video to 23.98 project, 50 video to 50 project)
Then open each bin from different projects in your main editing 25p project.

I don’t know what version of Media Composer do you use, maybe updated versions have already managed the mix frame rate difficulties, but this old thread could be helpful: https://forums.creativecow.net/thread/45/898136
See the last post by Michael Phillips in that thread – he posted a workflow for older versions of Media Composer:

i’ve done just the same here – export more than hundred sequences of feature film from FCP7 to Avid.
And after 2 days of testing i realize Automatic Duck suits better in my case.

It takes me only 2 steps with Automatic Duck instead of 4 with Davinci Resolve:
1) easy to export AAF directly from FCP menu,
2) easy to import AAF to Avid

With Davinci Resolve i need to do:
1) export XML from FCP,
2) than import XML to Resolve,
3) than export AAF from Resolve,
4) and finally import AAF to Avid.

And in my case Automatic Duck saves all the master clips names in sequences from FCP, while transferring projects through Resolve changes them to the media file names (it’s important only if master clips in FCP names by scene or something recognizable to editor)

There is also plugin called Axle Transfer for FCP – it imports and exports AAF.
But it’s pricey – $300 or something like that
