Should actually go OK with MDMA.
I love this stuff. Your description is spot on. A tactile erotic sort of swimmingly psychedelic first 3-4 hours... then a very delicate but cosmic psychedelic second wind SOME of the time... when it happens it is REAL sweet feeling... Feels like I have an ACTUAL THIRD EYE that opens up during this part, more so than on any other substance, like there's actually some sort of slightly tickly sensation in the middle of my forehead, just barely back behind the skin and skull on the surface of my brain... pineal gland orgasms perhaps? I've felt almost psychic during this part... senses seemed HIGHLY HIGHLY enhanced...
I remember quite vividly... this is a very true story I promise: Sitting on the porch one late spring morning at 4am during this second wind phase of 5-meo-mipt, smoking a post-orgasmic cigarette... the night Albert Hoffman died actually I think... I could actually HEAR individual petals from the magnolia tree blooms on the tree 25 ft away as they hit the ground... I heard miscellaneous industrial sounds at several loading docks miles away... the harmonious swell and ebb of a train horn's chordal tones off in the distance... then the mingled joyous cacophony of happy voices at a party wafted in on the wind from god knows where... and to top it all off with a few sparkly silver fairy dust glints - someone's wind chimes lazily swaying and tinkling in the distance somewhere... the heady & sweet intoxicating perfume of jasmine flowers from nearby bushes was like heaven itself and the soft feel of a slow breeze hitting my bare chest and closed eyelids I cant even begin to describe...
I could somehow feel the combined vibrations of all the minds on the planet wafting into space, like that jasmine flower scent wafting up away from the planet, being blown out into the galaxy as the solar wind gently blew the combined miasma, as the Aurora danced gently about both poles... what a magical evening, courtesy of 5-Meo-Mipt.
I had no music on, but it felt almost exactly like this sublime, divine sound (or, play the sample of track 2 "The Secret Place" from Brian Eno's record Apollo):

This was at a "Heavy" dose level by the way... which I built up to over a period of months by numerous experiment stgarting at LOW... someone new to the compound ought start with a light dose... some's "Light" could turn out to be your "heavy"... you have NO way to predict it.
I think all the combos you have lined up should play fine with it, but again it should be expressed that you need to gain a full experience, from first alert to final landing on this on its own to properly asses how it is going to affect you... it lasts a long time and can go thru shifts in effect throughout... you dont know your response till you let probably a few separate experiences with it ON ITS OWN to play all the way through.
To me its always been a rather special substance actually. Very malleable and amenable and good natured and friendly... I felt it "wanted" me to have a good time on it. It should he said though that others dislike it intensely, so do beware.
