Au/WSP Spending Sanity Check (Destination High Silver)

As the Christmas Event is coming to a close, I'm figuring I've extracted all the goodies I'm going to from playing way more hours and spending more on snowflakes than I'm willing to admit.  Ended up with a few decent pulls from the boxes as well, and have ended up with the following "premium" items in addition to previous purchases:

~12.5k Gold
~110 Million Silver
~29k WSP
Lancelot
Stalker 
Gepard
3x Orkan
2x Zeus
2x Aphid L6

I've been toying around in high silver prior to unlocking my fifth slot (4x 6/8 Heavies - Plasma Griffin, RDB Griffin, Thunder/Magnum Leo, KwK Natasha) and have really enjoyed the more deliberate and tactical pace of that tier.  It also avoids the plague of Magnum Gepards which I really do not enjoy facing at lower tiers.  As such I'd like to get myself setup with a competent High Silver hangar with the eventual intent of moving into Gold tiers as upgrade times permit.

Here's my current thought, and wouldn't mind some feedback to make sure that I am on the right track moving forward and not spending resources frivolously.  I'd also like to make sure I'm reasonably well set up to actually get beacons, which my previous hangar wasn't the greatest at.  I'm figuring two support bots and three bots to assault/beacons would be a decent setup.

1: Griffin 6/8 RDB (Already set up)
2: Lancelot 6/8 Thunder/Plasma (Weapons leveled, need to level bot) - Alternatively Orkans instead of Tarans
3. Galahad 6/8 Plasma (Need to purchase bot, Need to purchase Taran if I go with Tarans on Lancelot, Magnums already leveled)
4. Fury 6/8 KwK or Zeus (Have the KwKs leveled, would need to purchase another Zeus and level them all)
5. Not quite sure here, but would like to use the Aphids...  Aphid Orkan Griffin?  Aphid Stalker? Another Galahad with Orkan/Aphid? Alternatively DB Rhino?

My purchase list from the above looks like:
Fury (5k Gold)
Galahad (2.5k Gold)
Zeus (1.5k Gold)
Taran (~5k WSP)

I'd then have a good base of WSP for 3x Tridents for the Fury, or getting a Carnage (I have a lot of fun with the ThunderSchutze in Bronze).

Am I on the right path here?  Any advice on the Orkans vs. Tarans on the Thunder Lancelot?  Any guidance on the fifth slot would also be appreciated.  Thanks all!
