I bit the bullet and decided to write something ...

#!/opt/lampp/bin/perl -w

#use strict;
use Data::Dumper;

require "startup_cfg.pl";
#print Dumper(%VirtualHost);

print "RewriteLogLevel $RewriteLogLevel\n";
print "MaxClients $MaxClients\n";

for my $vhost ( keys %VirtualHost ) {
        foreach my $vhostdir ( $VirtualHost{$vhost} ) {
                foreach my $el ( @{$vhostdir} ) {
                        print "<VirtualHost  $vhost>\n";
                        foreach my $rec ( keys %{$el} ) {
                                if ( $rec eq "Alias" ) {
                                        foreach my $alias ( @{$el->{$r
+ec}} ) {
                                                print "\tAlias ". (joi
+n "\t", @{$alias}) . "\n";
                                        }
                                } elsif ( $rec eq "RewriteRule" ) {
                                        foreach my $rule ( @{$el->{$re
+c}} ) {
                                                print "\tRewriteRule "
+. (join "\t", @{$rule}) . "\n";
                                        }
                                } else {
                                        print "\t$rec\t" . $el->{$rec}

                                }
                        }
                        print "</VirtualHost>\n";
                }
        } 
}
print "Timeout $Timeout\n";
