Well, it still needs to be conceived and then tested. I immediately have doubts about having two exits from the spawn point (there would be three on "Nespider") - one leading to an off-road area, the other to a one-way path, and that's it.
Conceiving and testing - yes, that's necessary. I'm unlikely to do it myself, as it ruins my karma. At most, I can take a look and offer some advice. So, if anyone wants to try their hand at template creation, they are welcome.
