The pension I would normally leave on the income side, reducing your portfolio withdrawals but not part of your AA. If you plan on taking the lump sum option, then it is essentially part of your fixed income/cash allocation right now. Kind of with no growth unless you discount it a bit for being in the future.
The 401k should already be part of your AA if it is invested in something. Why is it not "available" now? Just because you are under age 59.5? If it's a sure thing (you are fully vested), and you can characterize the investments it contains as equity or bond or cash (and maybe it's just some type of annuity that you might count as income?), then it is in your AA whether you include it or not.
That may not be the AA you would choose if you had full control over all the accounts, but allows you to see where you stand. Nothing wrong with going all equities in one account to balance a bunch of cash/bonds in another account you have no control over if that gets you to your desired AA. In your case, you may just have to wait until 2018 before you can implement a plan to reach the AA you want.
