Need Help/Advice/Guidance with 10mm Basing

All,

Operation Barbarossa is fast approaching.  For some reason I decided to re-base my forces, wanted everything uniform, was tired of the hodge-podge of different colors and flocking.  So I'm almost finished, but I've run into a conundrum: I didn't want to base my vehicles because I plan on playing both summer, verdant battles and snowy, winter battles, and when you base your vehicles you sort of have to commit to either verdant or snow.  But I don't want to commit, I want to eat my cake and have it, too.  So the question is, how do you base vehicles that can be used for both the grassy steppe and snowy winter?

Take a gander at what I've got and what I've done so far.

So, here's the whole mess, Germans on the left, Soviets on the right.  It's not finished; I took everything I had and re-based it, then I had to buy some more stuff.  I had plenty of infantry but needed more vehicles, so I picked up some German halftracks and some Soviet T-34s, T-26s, a Ba-6, and a T-60.  I also picked up some Panzer IVGs (long 75s), Marder IIs, and Stug IIIDs (long 75s), so I figure the collection you have before you can take me all the way through the German 'gray' era, or up to summer of 1943.

Back to the basing issue: as you can see, the infantry are flocked in a nice, verdant mix, while the vehicles are not.  Just so you know, I have separate German and Soviet infantry and guns for winter, they're just not finished.  So I knew I'd need separate summer and winter infantry and guns, but want to use a single set of vehicles.  To that end, you  can see I have not flocked my vehicles, just painted them a nice muddy color on the base.

And the Reds.

So those look good, but what about the vehicles?

Here's my plan: leave the vehicle bases muddy brown in the spring/summer, then paint them white for the fall/winter, then paint them back muddy for the spring/summer of '42, then paint them white for the fall/winter of '42, then paint them brown for the spring/summer of '43.  Do you think that will work?  My concern is that the muddy-colored base is too jarring/ugly.  What do you think?

Here's what the muddy bases look like on the table at 'normal' tabletop distance.

So how does that look to you?  Can you stand it?  Should I?  Is there another alternative?

Let me lay some ground rules: I'm not going to buy another set of all those vehicles and do them again in winter colors.  I can't see flocking the vehicle bases for summer and then scraping it off and painting the bases white, I think it would be too frustrating trying to get all the flock off, would probably damage the basing gel I put down, and may even end up stabbing, scraping, and damaging the paintjob on the models.

I have thought of having two separate bases for each vehicle, one summer and one winter.  I lay on the basing gel, then pull the vehicle off, let it set, and flock for summer and paint white for winter.  Then I attach the vehicle to the appropriate base in a non-permanent way, so that I can put them on and take them off as appropriate.

So what do you guys think?  What would work best, or do you know of another idea, something I haven't thought of?

Thanks in advance!

Jack
