Sure, you can brew up your own liquid template pages and build up the template from the sites existing web templates. Before you do so i recommend reviewing www.xrmvirtual.com/meeting-details which will give you some pointers on how to put templates together.
Handy statements include block, extends and include
eg:
web template 'two colmn layout'
<div class="container">
<div class="page-heading">
<ul class="breadcrumb">
{% for crumb in page.breadcrumbs -%}
<li>
<a href="{{ crumb.url }}">{{ crumb.title }}</a>
</li>
{% endfor -%}
<li class="active">{{ page.title }}</li>
</ul>
<div class="page-header">
<h1>{{ page.title }}</h1>
</div>
</div>
<div class="row">
<div class="col-sm-4 col-lg-3">
{% block sidebar %}{% endblock %}
</div>
<div class="col-sm-8 col-lg-9">
{% block content %}{% endblock %}
</div>
</div>
</div>
web template 'links on left':
{% extends 'Two Column Layout' %}
{% block sidebar %}
{% assign weblinkset_id = page.adx_navigation.id %}
{% if weblinkset_id %}
{% assign nav = weblinks[page.adx_navigation.id] %}
{% if nav %}
<div class="list-group">
{% for link in nav.weblinks %}
{% if page.url == link.url %}<span style='font-weight:bold'>{% endif %}
<a class="list-group-item" href="{{ link.url }}">
{{ link.name }}
</a>
{% if page.url == link.url %}</span>{% endif %}
{% endfor %}
</div>
{% endif %}
{% endif %}
{% endblock %}
{% block content %}
<div class="page-copy">
{{ page.adx_copy }}
</div>
{% include 'Entity List' %}
{% endblock %}
