I really don't think the name of the church matters much to the unsaved. To many, any "church" is just filled with a bunch of hypocrites. We just need to be about living the christian life outside and inside the church that God has called us to no matter where or which church name we are under. God has shown me time and time again that he will always build his church, in his way, and sometimes it is in accordance with our cleverly devised plans. We are in our current churches and denominations due to the leading of God's Spirit. My early church background was Southern Baptist, to see "Presbyterian" on a church sign to me meant it was full of unsaved people, who were baptized as infants, who hadn't heard the gospel and might just have a homosexual woman pastor. The word "Reformed" had little historical church meaning to me and I did not know that "Reformed" Baptist churches even existed. There were some unmarked Reformed Baptist churches close by, but God evidently had other plans as they stayed unknown to me. Even after becoming a Presbyterian, in the early days I thought only two branches existed, PCUSA and PCA. Having OPC and ARP on a church sign meant nothing to me at that time. The meaning of words and abbreviations are only relative to the understanding that we have. If God wants me in the "Reformed Free Cookies Wretched Sinners Saved by Grace Infant Sprinkling Unpsalted Presbyterian Church", I think I will end up there regardless of the church name.
