Yes it is definitely possible.
I have a workflow that does exactly this. It does take a bit of work, but it is a real time saver once you get it working.
Out of the box Orchestrator has a workflow that allows you to clone a template. The only issue is it requires filling out a massive form, which takes way to long for administrators to fill out to be practical, and is to technical to hand over to the end user.
Depending on your OS and number of NICs per VM you are best to make a copy of the workflow "Clone, Windows with single NIC" and then make changes to hardcode a lot of these settings.
For instance if the person who is running the workflow chooses to build a production VM the workflow will select the production cluster. From there it will find the host which uses the least amount of memory, then checks if it is running with "if (System.isHostReachable(host.name , 100000) == true)". Or you could just select any host in the cluster that is running and allow DRS to balance the cluster.
Same thing for choosing a LUN.
Naming convention is simple enough if you know JavaScript. EG if your last production server built was PRODSERVER08, you can split out 08. Add one then join the sting to get PRODSERVER09.
I get an IP address from a database. Orchestrator has out of the box workflows for connecting to a database using JDBC. So create a database with all of your IP addresses, then you can assign and unassign IP addresses through a database query.
So yes it is possible. Depending on how complex your environment is, it may be quite monotonous entering all your environments configuration. You will need to know the basics of JavaScript. Just find a good tutorial that teaches you how to handle objects. Other then that I am sure you will be able to succeed.
