I'm very sorry but I can't figure out any scent that would smell much like Pasha minus the herbal notes But perhaps you could try YSL Jazz? It doesn't smell similar to Pasha, but has rather similar character IMO - classy, light, woody scent with good sillage, although Jazz is less formal. RL's Safari has thyme too, so it's probably too herbal to your nose too, but you better test it by yourself! I'm sure other basenoters will give you more suggestions and I hope you'll find our advice helpful!
Oh and about the longevity of Egoiste Platinum. I don't own it, but those times I've sampled it it has lasted very well on my skin - easily over 10 hours!
With best regards,
ps. No, to my nose Cologne and Issey hasn't smelled similar to each other, but perhaps that's how they develop on my skin and how my nose "sees" them!?
