Compliments are always welcome :-)

2 answers to your problem - a short and a long one.
Short: You could look at using VelocityOnlyLayout instead of
VelocityECSLayout. That way your layout template codes the entire HTML
document rather than just the body contents. Then you can use whatever
tags you want...
Long: It should be easier to configure the tools placed in the context,
like the page tool, and you certainly shouldn't be needing to override
TurbineVelocityService in this way.
So a long time ago it was discussed that there should be a means of
reading the tools to populate the context with per-request from
TR.properties rather than having them hardcoded into
TurbineVelocityService. I'm willing to look at making this happen, but
wonder if the work should be integrated with TurbinePullService as it
would be a very similar function, albeit on a per-request rather than
global basis. (Jason - thoughts?)
So if you're willing to wait whilst that gets worked out you could
achieve what you want that way.
