Hi amagee-
Have you tried this?
base_a.html
first {% block content %}{% block subcontent %}{% endblock %}{%
endblock%} last
base_b.html
{% extends "base_a.html %}
{% block content %}left{% block subcontent %}{% endblock %}right{%
endblock %}
template.html
{% extends (either "base.a.html" or "base_b.html") %}
{% block subcontent %}middle{% endblock %}
