If the musical function or intent is that these intervals should be equal, then the note is F#pp, that is, a double koron. One has (in any tuning) F#pp - Ep = F#p - E = F> - E = n, where n is the neutral second that Farhat uses, the same as Ep - D, then.
On the other hand, if it is lowered an unspecified amount, then when transposed, you will need another symbol that raises an interval so that the sum is M-m.
