BH2 Epi Conversion

Just got myself a basic BH2 with everything except the caliper thing for the XY stage, (i can print my own) for around 50 dollars on Ebay. I'm not that interested in biology and mainly want to look at some ICs. I already know you need the MSplan objectives, but I was wondering what other things do I need apart from the BH2-UMA to get the base 160mm standard biological version into something that can do reflected light? Will just getting the 180mm objectives and reflected light module be enough? Do the eyepieces need changing?
