Background
I understand this might be a rather vague question - and I apologize if it is too much so - but I am novice music theorist and think this question does have merit to it.
I am playing a 2-5-1 7th chord progression in the key of E major on my guitar in the following voicing:
F#m7 B7 Emaj7
E|--9-----7----7--
B|--10----7----9--
G|--9-----8----8--
D|--11----7----9--
A|--9-----9----7--
E|--------7-------
Which sounds great, obviously, as 2-5-1 are well-established chord progressions.
What I am trying to accomplish
However, when I play through it a second time, to switch things up, I conceptualize either a different second chord or an added chord in-between the second and third chord of the progression, like so:
F#m7 ? Emaj7
E|--9-----?----7--
B|--10----?----9--
G|--9-----?----8--
D|--11----?----9--
A|--9-----?----7--
E|--------?-------
or
F#m7 B7 ? Emaj7
E|--9-----7---?---7--
B|--10----7---?---9--
G|--9-----8---?---8--
D|--11----7---?---9--
A|--9-----9---?---7--
E|--------7---?------
Where the new chord in either example would be in a higher pitch/octave that resolves to the 1 strongly. I feel like I have heard stuff like this before and can conceptualize the sound I want to make, but can't quite find the voicing on the fretboard.
What I have tried
I have tried B7 higher up the neck along with Amaj7, C#min7, D#dim, and D#m7b5 along with playing triads of each on the first three strings to no avail. I can't quite shake this chord I'm thinking of. I can hum it, but still no luck finding it, so I decided to come ask here.
Question
So ultimately my question is, is it common to add to or alter a 2-5-1 chord progression? If so, which chord(s) work well both in general and specific to my example? Apologies in advance if I misspoke on anything - again, I am a novice theorist trying to learn from others in the community.
