I do not think Aleph is a good faction to demo with.
opinion-
Aleph has a lot of special rules that many factions do not have, and the models are deceptively powerful for their size.
also the models you have are good, but not for a demo game.
You pretty much are forced to demo hacking since most of your models are
REMs, which just makes the game more complicated to demo...
the Pan-O starter has 6 models, comes in at 126pts or so and 1.5swc
to build a balanced force to demo against, you want around the same model count and as close to possible for the same cost.
The Asura is 68pts which is a little more than half the cost of 126, so honestly You should not include it.
This leaves your best Lt Option as the deva. Which you don't list any devabots as owning and do not want to buy more models so already this is not good.
I would proxy the dakini tacbot with
HMG as a devabot, and do something like the following:
if you plan to
not use LTs:

tbh for demo I like the first list better because it is close to the same model/order count as the Pan-O starter.
Also both sides have models that are around the same cost/power.

I like this list the least. Yeah the models are all good, but the player has an order pool of 3, versus the other players order pool of 6. It will feel lopsided in a demo.
