You just need to make a small change to your code. You can write into a variable if you don't close the tags immediately. This way you preserve your structure, but you can access it with your code.
<xsl:variable name="content">
<Configuration>
<ProductLineItem></ProductLineItem>
</Configuration>
<Configuration>
<ProductLineItem></ProductLineItem>
<ProductLineItem></ProductLineItem>
</Configuration>
</xsl:variable>

<xsl:variable name="GeneratedStructure">
<xsl:for-each select="$content/Configuration">
<ConfigItem>
<xsl:variable name="ConfigurationPos" select="position()*10"/>
<xsl:variable name="ProductLineItem">
<xsl:for-each select="ProductLineItem">
<ProductLineItem>
<xsl:variable name="ProductPos" select="$ConfigurationPos+(position()*10)"/>
<ProductPostionNumber><xsl:value-of select = "$ProductPos" /></ProductPostionNumber>
</ProductLineItem>
</xsl:for-each>
</xsl:variable>
<xsl:copy-of select="$ProductLineItem"/>
<Subtotal><xsl:value-of select="sum($ProductLineItem/ProductLineItem/ProductPostionNumber)"/></Subtotal>
</ConfigItem>
</xsl:for-each>
</xsl:variable>
<xsl:copy-of select="$GeneratedStructure"/> <!-- This will output the content of the variable -->
<xsl:for-each select="$GeneratedStructure/ConfigItem/Subtotal">
<xsl:element name="Subtotal{position()}">
<xsl:value-of select="number(.) + 10"/><!-- You did not specify if it should simply add 10 or add how often the for each loop repeats. Fix this for your needs. -->
</xsl:element>
</xsl:for-each>

Current output:
<ConfigItem>
<ProductLineItem>
<ProductPostionNumber>20</ProductPostionNumber>
</ProductLineItem>
<Subtotal>20</Subtotal>
</ConfigItem>
<ConfigItem>
<ProductLineItem>
<ProductPostionNumber>30</ProductPostionNumber>
</ProductLineItem>
<ProductLineItem>
<ProductPostionNumber>40</ProductPostionNumber>
</ProductLineItem>
<Subtotal>70</Subtotal>
</ConfigItem>
<Subtotal1>30</Subtotal1>
<Subtotal2>80</Subtotal2>
Please consider checking your spelling, because it is hard to assume what variable you mean, if you call it by other names.
EDIT: I did edit it to your needs. Although it is not clear what you exactly want to do. If you show me some input and expected output I could fix this.
