Personally I have only two rules which I try to stick to when building my units:
- Does it look cool? - use it
- Is it absolutely not 30k? i.e. a complete set of Mk8 armour? - don't use it.
Let me tell you where my 30k vision comes from... it mostly comes from Horus Heresy Collected Visions, published in 2007, and later re-issued as Visions of Heresy in 2013. It was so good I brought it twice! Much of the art is the same but with lots of the Black Library book covers included in the latter.
The rest of my vision comes from my early gaming experience as a teenager. Back in 1994 there were lots of Space Wolves metal miniatures in production, mostly sporting Mk6 armour, which at the time was seen as 'Heresy' armour. Which is why you'll see a hell of a lot of Mk6 in my army.
In terms of kits I generally mix 40k Space Wolves boxes with Forge World resin and am pretty happy with the results. But I use '40k' bikes, missile launchers, plasma guns and melta guns because I generally don't like the '30k' version. And I know others do the same with other pieces. Although I don't feel justification is necessary for using what I like, I wanted to share some pictures from Visions of Heresy which show some of these '40k' bits 'existed' in 30k:
Here's some Mk4 armour in one of John Blanche's concept sketches.
And here's some completely unknown mark of armour... Mk6 legs? Mk4 arms? Mk8 torso? What I'm saying is, there were numerous styles of armour, Forge World have only produced the most common one. Pretty much anything goes.
Here's a more recent piece of art by Neil Roberts clearly showing Mk7 legs with a Mk2 helmet. Talking of things we do and don't see in these books, you know something we don't see at all? Mk2/3 back packs. Take a look, they are all Mk4/7 style. This style of backpack only came about when Forge World started producing miniatures, back in 1994 they didn't exist! So don't talk to me about what is canon; canon is only canon until the designers and writers change it, and this is a fluid hobby people!
Here's some '40k' melta guns used by a guy riding a '40k' bike.
Here's some drop pods, long before they existed as a miniature.
Here's a Space Wolf carrying a lasgun!
'40k' attack bike.
'40k' terminator armour (naughty Imperial Fists!)
'40k' plasma gun.
I'm putting this out there because ever since Forge World started issuing rules and miniatures for 30k there have been a number of *insert expletive* people out there calling people out for using 40k bits in their forces and I'm a bit tired of it. Yes the purists have paid a fortune for their resin, me included, but if someone wants to use a cool bit, or save some money by using plastic Rhinos (which are loads easier to put together, lets be honest) so they can buy a Spartan, so be it. Thankfully my hobby circle thinks along similar lines to me, if it looks cool and you can invent a fluffy justification for it, use it.
Remember, these are your space toys, it is your hobby, so do what ever makes you happy!
