Yes it is possible but it is a bit of work to get it working. What you have to do is change the settings of the dedicated server to host on a different port then your normal server so for example, your normal server hosts on ports 28000-28030, then you would have to change your dedicated to host on a different range of ports like 28031-28060. To do this start up blockland normally change the server host ports in the advanced menu in the create server thingie. Then exit, and start your dedicated which should be hosting on those ports you set. Then you can start up blockland and start a normal server, but make sure you change the ports its hosting on or else it wont work. One problem you may have is if too many people connect to your servers because most home internet connections have VERY little upload bandwidth, so you may cause EVERYONE to lag horribly if you dont have enough upload bandwidth for like 60 people, which I'm pretty sure you don't. Although 2 servers of 8 people each should work ok, but this all depends on how much upload bandwidth you have. Good luck.
