In a series line level effect loop in my amp, could two simple mono to stereo 1/4" adaptors be used to create what I am looking for?

For example, I could split the signal with a mono to stereo 1/4" adaptor where one out goes to the TF, set to wet only, and have the other out of the adaptor goes to a similar 1/4" adaptor that receives the TF on one side and the dry signal from the first adaptor which then is returned to the amp — and thereby preserving the analog signal?

Are there technical reasons why this would not be workable?
