Go with Tbones suggestion - don't buy anything new until you consolidate those GFCI outlets. Figure out which circuits can be combined based on load - wire them together in a junction box fed by one GFCI outlet near the sub panel making sure to wire the downstream legs for protection by the GFCI outlet (replace unneeded GFCI with standard outlets). Hopefully, as you expancd your show you will add/replace with LEDs so your power requirements will drop...
