An option to consider is swapping your 2s for 1s, i.e. the first generation speakers. Putting aside discussion of which is the "better" speaker (since it has been well covered in this thread), the first generation speakers have flush metal grills, are wider, deeper (and the FS is shorter) and are pretty much kid-, cat-, vacuum cleaner-, etc. proof.
It has been a while since they have been on sale from NewEgg, which used to be a regular occurrence. Perhaps you could arrange a local swap with an owner of a comparable set of first generation speakers.
Bookshelf speakers on stands will be far more vulnerable than floorstanding speakers and represent a worse investment since the floorstanding speaker are effectively the same speaker fixed on a sturdy stand with an extra woofer and better performance (and price, depending on what stands you buy).
The center channel is mounted below my projection screen.
If you have space and depending on the size of the screen, moving the speaker(s) behind the screen is an attractive option in most cases especially if the screen is acoustically transparent and will enable you to raise it to the same tweeter level as the mains where it belongs. I hope you don't have the center on the floor, even if it is pointing up to the main listening position. Doing this may also help you protect your existing speakers and save you the time, effort and cost of changing speakers just to try to keep the safe.
I am running a BIC F12 subwoofer which I plan on upgrading within the next 2-3 years. I don't want to spend that much more money than I already have
Here's your real dilemma. By far the biggest upgrade in sound will come from getting a better sub - preferably (at least) two, however that better sub will cost more than your speakers. This has also been discussed at length in this thread, including advice on what and where to buy new and used.
FWIW, I have SP-FS51-LR, SP-C21 and SP-BS41-LR with dual SVS SB1000s in my bedroom theater and two SP-BS21-LRs in the basement.
