You\'ve got the makings of my current # 1 mix there. Acqua di Gio and NPA mixed 5:1 is a great combo, I just don\'t know how roller-friendly it might be. Works nicely in an atomizer though. ( L\'eau d\' Issey is another edt that blends well with NPA.)
SPMO and NPA is another mix I\'ve read good things about. It\'s one of the tried and true Jambat mixes (JB #2), and the standard 7:3 ratio seems appropriate for a fragranced product with SPMO\'s scent intensity. But 3:1 might work too.
( SPMO is an A-Nol only product with an unspecified phero content.)
RM presents something of a quandary. Its scent is quite intense, and its phero content cries out to be diluted. I haven\'t figured out just what to do with it yet. I mixed a bit of vegetable glycerine into it with the dual intent of thickening it up and cutting the intensity of both its fragrance and phero power. It worked to a degree, but not what I\'d call a resounding success.
I usually shy away from mixing two fragranced products together, but I\'m thinking about adding a little SP Vanilla or Citrus oil to a very small quantity of RM to give it a little A-Nol kick as well as sweetening it up some. RM is a tad spicy for my tastes. You might try mixing a tiny batch of RM and SPMO (like a few drops of each), but don\'t get your hopes up.
I\'m not familiar with Majestic Aura. Is it a phero product?
