A single kind of bush would likely look better.

Different bushes likely will grow at an uneven rate and, unless they don't keep their leaves year round, they'll not cover your foundation as you wish. You could replant those you've purchased in a circle with the tallest growing one in the center, and create a patio around or beside them. Then move the really nice blue planter from the stoop (and out of the way) to the new patio.

Aucuba bushes can grow over 6' tall and are often found around the foundation of older homes in the southeast. I have two rows of them and recommend them highly.

My yard adjoins a national forest so deer nibble away at my azaleas, stunting the blooms on all but the white azaleas, but have yet to bother my aucuba bushes. Voles try to eat any bulb I plant except iris -- they've left them alone (thus far).

In front of the planting area around your foundation and around any planting area you create in your yard, adding an outline of flat paving stones with the tops level with the ground helps define the planting area while making mowing easier than a row of stones or landscaping post above ground would. Flat paving stones let you define where you'll add mulch and throw your crushed egg shells (serve as bone meal) and work to keep the area weed free, leaving the rest of the yard to mow.
