Applying for fellowships in the UK with different UK host scientists

I have finished my PhD recently, and now I am applying for postdoctoral positions. I am not a UK or EU citizen. Assume that I would like to apply for two different fellowships in the UK (for example, among those described here), with different UK based host scientists. Let's say I would like to apply for a scheme A together with X and for a scheme B together with Y, where A is not equal to B and X is not equal to Y.

Could such "double application" hinder my chances?
