How fixated are you on a 1P "tent." I always recommend a 2P pyramid, like the MLD DuoMid, as a solo shelter.
Mids are pretty much the shelter to have if you can only have one. A 2P is a palace for one person, giving room to sit up and change clothes or cook inside, and has enough room that you are unlikely to brush your nice down sleeping bag against whatever condensation accrues. Almost all are still well within your desired weight range. They're simple. Rugged. Fast and easy to pitch. They can use your trek pole as the center pole, though many might need a polejack or a rock under the pole. Great in wind and bad weather- just bring four stakes in nice weather but you can nail it down with a dozen if you need to in high winds. Good in all but the most massive snow loads. And in any but the worst weather you can just leave the door open for nice views.
A simple/cheap silnylon bivy can act as both a groundsheet and bug protection if you need it.
And a 2P pyramid can of course house two people in a pinch.
What's not to like? Well, unless you're one of those freaks who has an irrational dislike of center poles and/or can't figure out how to cant them. ;)
But if you are really set on a fully-enclosed bugproof tent with a floor then, yes, I don't see the point of a pyramid with an innernet.
