This looks like a very straightforward transformation, you don't make it
clear where your difficulty lies. Or are you just asking if someone can
write the code for you?

The coding pattern for this is to write an "identity template" that copies
elements unchanged:

<xsl:template match="*">
    <xsl:copy-of select="@*"/>

and then supplement it with overriding rules for elements that need to
change, for example

<xsl:template match="rpc">
  <rpc rpcname="Sikorsky">

<xsl:template match="applic"> 
    <model model="{//modellic}">
      <mfc><xsl:value-of select="../rpc"/></mfc>
      <pnr><xsl:value-of select="//modellic"/></pnr>

I don't know if XMLSpy has the facility to apply a transformation to 1000
input files: I suspect not. A good tool for this might be Kernow.
Alternatively, XSLT 2.0 has facilities for selecting a collection of input
files and creating a set of corresponding output files within the language
