You could but I find the EI core types to be detrimental to sound. The issue is that the magnetic field generated by a toroidal transformer is circular. The hole in the middle is necessary for aiding the magnetic field flux. IF you use a VPI Magic Brick, placing two edgewise on either side of the toroid gives significantly better results than one diretly over the middle.
I have in the past purchased large toroids: basically unmagnetized speaker magnet material. These work very well on top of toroidal tranformers I usually augment them by wrapping them with copper tape and generally ground that tape.
Your chokes would work well on the traditional EI transformers, however. Align the choke laminations with the lams on the EI transformer for best results. Well, at least that has been my experience.
Again YMMV.
