No, is the simple answer.
BizTalk is a messaging platform (-ish), and not really related to web
sevices per se. Its web service-friendly credentials come from two main
angles:
1. Business processes modelled as Orchestrations within BizTalk can
"consume" (i.e. call) external web services.
2. Orchestrations' entry points can be exposed via web services, allowing
external parties to submit messages to BizTalk via SOAP. When an
orchestration is exposed in this way the web services generated are still
hosted within IIS as normal .aspx pages; code behind the web services uses
the BizTalk API to push the contents of the web service request into BizTalk
as a message. BizTalk is not a web server, so can't host a web service
natively.
Converting your existing web services to run as orchestrations within
BizTalk might have some benefits, but BizTalk is designed primarily to
process messages asynchronously, and synchronous request-reply scenarios are
not always easy to get right (though they can work.) See
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnpag/html/eappint-ch04.asp ,
under "Request/Reply" for a simple explanation of how you would implement
such a scenario.
Implementing BizTalk successfully is a "non-trivial" process, and without a
well thought-out plan of action it would be hard to recommend it simply for
the sake of it?
