shoot man you don't want two trainers do you? I would build a fourstar 40, 60, or 120. as a good solid second plane. Some people even use these as trainers. If you build a fourstar 40 (very easy to build, just as easy as an LT-40 or PT-40) you can take out all the radio gear and engine from your trainer and put it into the fourstar (i did this as well, took out the gear from my Alpha trainer and put it into a kit build FourStar 40). I just think you will get board of a trainer real fast and then you will have two of them instead of a step up aerobatic lowing trainer. just my two cents but the four star is really fun! i'm about to build a 120 size one with a 31 cc gasser.
