So, I'm potentially playing in a PS tournie as one half of a doubles, under the following conditions:
Doubles Tournie
1000 points per player
Allied with Blood Angels/Space Marines
No restriction on what races can ally
Allowed IA/Apoc as long as it isn't super-heavy/gargantuan/formation (doesn't make any difference to us AFAICS)
3 Stratagem points to spend (as a pair)
1-3 Bastions for the defender
Attacking and Defending lists can be different

My "other half" will be using his BA Successors as either BA or SM, depending on what units he decides to use.

Now, as you may have noticed in the painting section, I'm not exactly a prolific painter , so my options are limited:

Dark Eldar - some painted, reasonable range of options, paint scheme is fast.
Marines - I have 1k painted to 3 colours, but it's infantry based around Tacs and Devs, and I intend to repaint it UM, so I don't really want to add more.
Daemonhunters - some painted bits, can fill points with either my marines, or my mates, other bits I could paint in time.

Now, I think DE at 1k will suck. IMO they need 2k minimum and a tri-Portal list is the only up-front feasible list. So, I'm ruling them out as I don't have 30 Grotesques or enough points to run with it IMO.

Marines I think I just don't have the models to run a decent list. The Devs have to wait a turn to fire, and 8 Lascannons isn't an effective way to take on Bastions.

I'm open to persuasion that I'm wrong on the above two....

So, I started thinking about Daemonhunters.

Attacking

I've got the Termie box, so if I added Stern (as himself) I could have 2x3 Termie squads, the second with a GM maybe.
Melta Strike is an obvious choice from the HS section.
Callidus Assassin.
Inquisitor (to take Assassin).

That's around 6-700 points.

I could just give the Inquisitor a bolter, or I've got one in TA with a Psycannon that could join a squad.

I could get out 2 minimum-sized squads of ST with dual meltas for more Bastion-busting.

I guess that leaves about 100 points which could buy a squad of PAGKTA for some more straight assaulting.

Dreads and LR are out as I wouldn't do them without the FW bits (although FW delivered my last two orders in less than 5 days, and someone else I know as well - so maybe not impossible).

Thoughts?

Defending

I'll be honest, I'm having a bit of trouble with this part. There are IG and SM allies available as well, although to get the useful stuff I'd be bound by the 2x Troops required (not an issue as I've got them, but only if doing so isn't a handicap). It did occur to me that 2x Tactical Squads in Bastions with Teleport Homers could be very helpful for bringing in the above Termies and possible PAGKTA.

Obviously a mystic is going to be useful, so the cheap Inquisitor could appear, which opens up the Callidus again (although I could quite easily buy a different one).

Any comments on either half appreciated
